You. A large part of the game in understanding your perception of the events going on around you and how you relate to them. So "you" is the important factor. I also kind of agree though that there isn't a need to emphasize any single word.

I always thought the emphasis was on world, actually... now that I think about it. but out of the two, I suppose you would also work.

There is stress on World. It's also on Ends. I just do not know if, after that, the third stress goes on End or You. I don't know if the stress pattern is

well, you'll stress it regardless, I'm wondering how you do it internally. You stress different words in sentences regardless if you do it consciously or not. In most cases it doesn't matter but in some it does. In this case, the location of the stress changes the meaning of the sentence.

"Listen up, Phones. The world ends with you. If you want to enjoy life, expand your world. You gotta push your horizons out as far as they'll go."

When he told that to Neku in the game the title made sense. The world exists as far as you know of it. Live in your room all day and the world seems like shit. Go out and experience places, events, and people and it will seem pretty open. The world is as big or small as you make it.
